Just got it last night.
My only gripe is that you have to back up to block. I thought this was a flaw in Mortal Combat as well and this game is from the orignator's of MC.
Fast graphics. A less complicated system of moves than Tekken.
Every time you hit your opponent your 'chi bar' increases. When it maxes you can attack with your chi or heal yourself.
Not very realistic of course but a pretty standard power up methodology.
